你这个说法,明显落伍了吧。华为的四核手机已经做出来了,三星也刚出了 一款新的。很快Android高端手机,就是以四核为主了。 GPU也是多核,华为的四核手机,据说GPU是16核。 http://www.phonearena.com/news/Huawei-brings-home-grown-K3V2-qu Huawei shocked us not only with the impressive Ascend D quad, but also with the silicon powering it - the K3V2 quad-core processor inside it was made by Huawei itself and based on ARM’s Cortex A9 architecture... The K3 chip comes with a 16-core GPU, which beats the 12-core graphics on Tegra 3 and 8-core GPU on Tegra 2.

对做这一行的人来说,多处理器/多核设计可以节能,是textbook knowledge。 这个想法在embedded computing里已经用了很多年了。 你不信,就看看课本是怎样说的吧。 http://books.google.com/, search "Computers and Components" Computers as Components: Principles of Embedded Computing System Design, Morgan Kaufmann Publishers, 2001 By Wayne Wolf, Princeton University, Member of National Academy of Engineering Quoted text: Chapter 7, page 353 "Chapter 7 Multiprocessors Introduction Multiprocessing -- using computers that have more than one processor -- has a long history in embedded computing. A surprising number of embedded systems are built on multiprocessor platforms. In fact, many of the least expensive embedded systems are built on sophisticated multiprocessors. Battery-powered devices that must deliver high performance at very low energy rates generally rely on multiprocessor platforms; this description fits a large part of the consumer electronics space."
你至少看看全,看到355页吧。再说了,你自己引用的话: Battery-powered devices that must deliver high performance at very low energy rates generally rely on multiprocessor platforms。 作者说得是embedded computing high performance vs cost的平衡。对于手机这类不 需要常常high performance的device, 太多核只是一种浪费。 双核的iphone4s和同样 工艺的四核iphoneX一起高载跑4线程, 那当然是四核的省。 如果是待机呢? embedded system设计针对性很强,high performance embedded system的代表就是程 控交换机。 所以正确是说法是,多处理器/多核设计可以在高载的情况下(对多线程程序)比单核 更高效, 所以更节能。

“多处理器/多核设计可以在高载的情况下(对多线程程序)比单核更高效, 所以更节 能。” 你会不会仔细看看我说的话,看看那本书,再回头看看自己说的话?那书是啥时候写的 ?iphone/ipad是啥时候有多核的? 靠,对业余的说点东西真费劲. 还是个不愿意看书的业余。 --------------------------------- Battery-powered devices that must deliver HIGH PERFORMANCE at very low energy rates generally rely on multiprocessor platforms; IS NOT THE SAME AS Battery-powered devices generally rely on multiprocessor platforms TO SAVE POWER ------------------------------------
